McCONNELL: A PARASITE OF THE HESSIAN FLY

thorax remains but this is enough to prove that the specimen was a 
wingless Eupelmine similar to the species in this country and not a 
Mira. What is left of the specimen agrees perfectly with your speci¬ 
mens, so far as I can see, so there seems to be no reason to think that 
the determination of our species is not correct. The name Mira 
should not be used for the genus, however, since Mira as now under¬ 
stood is not a Eupelmine.’’ Still later Mr. Gahan wrote regarding the 
generic position of this parasite: “Eupelminus is the generic name 
applied to a lot of Eupelmines which are wingless or with rudimentary 
wings. I really do not think that this is generic but for the present it 
will probably be better to use the name since it does identify the species 
to some extent. The name to be used then will be {Mira) Eupelminus 
saltator Lindm.” 
The opinion has also been expressed by Mr. Gahan that this is the 
same parasite which Mr. W. J. Phillips of the Bureau of Entomology 
has reared from the galls of various species of Harmolita {Isosoma). 
While our knowledge of this species as a parasite of the Hessian 
fly is by no means complete, yet it seems worth while to place upon 
record the fact of its occurrence in this country together with the facts 
we have accumulated regarding its life-history. The biological data 
are based on experiments conducted in the laboratory at Hagerstown, 
Md., chiefly during the season of 1916. The writer has been aided 
in the collection of material upon which the field records are based by 
Messrs. P. R. Myers and P. H. Hertzog. Mr. Myers has also given 
very valuable assistance in rearing the field puparia and has carried 
out some experiments on the parthenogenesis of this species. 
Distribution 
Lindemann’s specimens were reared from puparia which he collected 
at Moscow and in various governments of central Russia. He states 
that he has never found the species abundant, but it is probably wide¬ 
spread in Europe, and was undoubtedly introduced into this country 
at an early date in infested straw. There are apparently no other 
records in literature. 
We have reared it from the following nine localities in Pennsylvania: 
Carlisle, Andersonburg, State College, Danville, Montoursville, Lin¬ 
den, Butler, Greenville and Linesville; from Hagerstown and Brad- 
dock Heights in Maryland; and from Strasburg and Woodstock in 
Virginia. Mr. Phillips has reared it from Harmolita material from 
Michigan, Indiana, Ohio, New York, Pennsylvania and Virginia, and 
probably from other states. 
The species has not been an abundant parasite of the Hessian fly 
during our investigations. The greatest number were found in a field
